CAR CONSTRUCTION Filed March 8, 1928 Patented Oct. 8, 1929 UNITED STATES PATENT OFFICEr WILLIAM H. MINER, OF CIIAZY, NEW YORK, ASSIGNOR TOW. H. MINER, INC., 0F CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE CAR CONSTRUCTION Application filed March 8,

rilhis invention relates to improvements in car construction.

In the operation of railway passenger cars, it is highly desirable that means be provided to prevent separation of the body and truck holsters in the event of a collision, in order to eliminate or minimize danger of telescoping of the cars. Vith the types of bolster locking pins heretofore provided for the above purpose, much difficulty has been encountered in the use thereof on certain classes of cars, particularly dining cars. As well known, most passenger cars employ sixwheel trucks, the center axle of which is directly located below and adjacent the center pin, so that it becomes either impossible or exceedingly ditlicult to insert or remove the bolster locking pin from the under side of the holsters whenever it becomes necessary to remove the car body from the trucks in making repairs.y This difiiculty has been partially overcome by inserting the locking pin through the floor of the car from above the holsters, but this expedient is unsatisfactory, especially inr the case of dining cars. In dining cars, the heavy kitchen range is almost universally located directly over the centers of one rset of holsters, and consequently, when necessary to separate the car body from the trucks, it has heretofore been necessary to lirst remove the kitchen range. Obviously this involves much labor, expense and delay in carrying out the desired repairs. p

One object of my invention is to provide a holster locking center pin, especially adapted for those cars where the pin cannot conven iently be inserted or removed from the under sides of the holsters and which improved pin will readily permit separation of the body and truck holsters without the necessity of obtaining access to either the upper side of the body bolster or the under side of the truck bolster after the pin has oncebeen applied.

Another object of my invention is to provide a bolster locking center pin which may be rendered ineffective temporarily by merely withdrawing removable locking means associated therewith, which removable means 192 Serial No. 260,025.

may be withdrawn laterally and which is ac cessible at one side of the bolster.

Other objects of the invention will mere clearly appear from the description and claims hereinafter following.

In the drawing forming a part of this specification, Figure 1 is a vertical sectional view taken diametrically of the center bearing portions of the body and truck holsters of ak passenger car and showing my improvements in connection therewith, certain of the parts being broken away in order to better accommodate the figure on the drawing. And Figure 2 is a horizontal sectional view, corresponding to the line 2-2 of Figure 1.

In said drawing, A indicates, broadly, a body bolster of a passenger' car, and B a truck holster, the latter being generally in the form of a spider, but the details of which are unnecessary of illustration or description in connection with my invention, inasmuch as the details of the holsters may vary, as will be obvious. The improved locking center pin comprises two elements C and l) and a retaining key E, the details of which will be hereinafter set forth.

The body bolster A is, or may bc, of any well known construction, and, as shown, is formed with a vertical elongated hub section 10 having a vertically extending, cylindrical openin 11 for the reception of the center pin. At the upper end of said opening 11, the body bolster is provided with a rectangular horizontal shoulder 12 and the opening upwardly thereof is of similar cross section, as indi cated at 13. Aportion of the car floor is indicated at 14, between which andthe top of' the body bolster A is an annular collar or sleeve 15, through which the upper element C of the center pin may be entered from above, the floor opening being closed by any suitable means, such as the cover plate 16.

The body bolster A is preferably formed with an integral center bearing plate section 17 co-operable with a preferably detachable center bearing plate 1S, the latter being mounted on the truck bolster B and confined in proper position by sections 19-19 of the truck bolster. The center plate section 17 is shown as formed with a female recess 20 in n@ oo nl l .tending openingsBS-BB l rovided i which is entered the male section 2l of the center bearing plate 18.

The truck bolster is formed With an unper horizontal web 22 having a center l opening 23, at the bottom ot which is provided an annular shoulder 24e. The truclr bolster also has vertical Web sections 25 below the center pin opening and to Which is ad pted to be secured, as by rivets 26, a sustaining plate 27.

` he center pin proper is preferably comprised of two substantially like sections C and l). Each of said sections is formed with a head ot suriicient diameter to prevent pasthrough the center' pin openings in the bols The head 28 of the section C is nreierably square and the head 128 of the sect-ion D is preterably of annular torni. t ofc sine ot the head, each section ls provided blu ine-er the center pin openinw. Flach cylindrica fection 29 is cut away on an ogee curved surface 30, as clearly shown in igure l, the ogee curved surfaces being complemental, so that when the tvvo pin sections C and are assembled, as shown in Figure l, said sur- 'iaces 30 will meet and thus provide a center pin et tull and continuous cylindrical i'orin trom top to bottom. The upper sect-ion C may be provided with a flange 31 on the upper end thereof, which flange may be suitably apertured so as to receive a hoolr or the like, for withdrawing the pin upwardly should this become necessary. is Will be clear from the drawing, the head 28 oi the upper section C normally rests on the shoulder l2, said section C being entered from the top and the head of the lov/er section l) normally rests upon the supporting plate 27, or at least is prevented from falling out thereby. Any tendency to separate the holsters vertically .villresult in the head 12S ot the lower section D engag- With the annular shoulder 2li, as will be obvious.

The pin sections C and D are provined will aligned transversely entendino' openings 32,

which are also aligned Y 7ich transversely ezi- Walls of the hub section it) ot the body The retaining lrey E is entered through the aligned openings 3Q and 33, shown in the drawing, and is .held against accidental removal by any suitable means, such as cotters 3e entered through theY key E on opposite sides ot the hub section l0. YSaid key E is preferably in thetorm oiC a relatively hear-:y bar ot rectangular' cross section, With the Widest dimension extending v rtically or par allel to the axis of the center pin so as to thereby obtain the maximum strength of the key against shear When 'there' is any tendency ot the holsters to separate vertically. F or convenience, the ley E may have a suitable hand-hold 3,5 at its end to facilitate insertion and removal.

ir't a cylindrical stom 29 conforming to the such as sleeping and dining cars.

#from the unc er side of the truclt bolster B and, When in place, the retaining plate 27 Will be applied and the attac nnent thereof may be made permanent. l,"Vith the tivo pin sections G and D associated With the body and truck holsters, respectively, it is evident that the car body may be l wered upon the truclr and the tivo pin sections Will be tiereby assembled. liv/viren assembled, the lrcy E is inserted, thus obtaining the desired locking between the body and truck bolsters and preventing` vertical sepa ation thereof, in the event ot collision or other accident. Should it be desired to separate the car body from the truck bolster' at any tiv Ae, to etl'ect repairs, it is only necessary to Withdraw the lrey E, leaving the pin sections C and D associL ed -with their respective holsters it. and B.

employing' a square head 2S on the pin section C and a correspondingly shaped recess to receive it, the position ot the pin section with respect to the body bolster is maintained and turning prevented, thus insuring alignment ot the lrey receiving openings oi' the bolster and said pin sections. l)ue to the ogee engaging surfaces ot' the tvvo pin sections, the section l) will also be positively positioned to maintain its lrey opening 32 in alignment With the openings 33. Y

lfith the arrangement shoivn and described,

it is evident that I overcome the di'jiculties and disadvantages inherent in toriner types of center locking pins, particularly where such pins are used on passenger equipment, The arrangement is such that no special designs of bolsters are required and the locking center pin may also be manufactured at compari tively small expense.
